This guide will share how to determine what size HVAC system your home needs. We’ll explain why HVAC unit size matters, factors that impact your decision, and why working with a professional HVAC company is critical.
Why Getting the Right HVAC System Is Important
Having an HVAC system that is the right size for your home ensures continuous year-round comfort. Choosing the right size HVAC system can impact the lifespan of your unit and its energy efficiency.
Too Small Issues
An undersized AC or heating system can lead to constant runtimes that overwork your system. When your unit is too small, you also may encounter much higher energy costs as your system works overtime to heat and cool your home. Additionally, another common problem with an HVAC system that’s too small is uneven heating or cooling throughout your house.
Too Large Issues
When your HVAC system is too large, it can cause short cycling. A larger unit will reach the desired temperature more quickly, which can cause it to turn on and off frequently. Short cycling wastes energy and can cause unnecessary wear and tear on your system. This leads to higher maintenance costs and a shorter overall unit lifespan.
What Affects Your Decision
There are several factors that come into play when sizing an HVAC system for your home.
Type of System
The type of system will dictate what size you will need. There are three primary HVAC types: split systems, ductless systems, and packaged units.
Split systems are a combo of an outdoor air conditioner or heat pump and an indoor furnace. Ductless systems have a single outdoor unit that is directly connected to one or multiple indoor units. Packaged unit systems connect directly to your home’s ductwork and use a single outdoor unit.
Square Footage of Your Home
The size of your home will significantly impact which HVAC system you choose. Bigger homes will require a larger HVAC system to meet heating and cooling demands. Homes with lower square footage may only require a small unit.
Windows & Doors
The number of windows and doors in your house should be taken into consideration when sizing your HVAC system. Doors and windows transfer heat and cold in and out of your home.
The more windows and doors you have, the harder your HVAC may need to work. Sun exposure also is important to consider when choosing an HVAC system.
Ceiling Height
Ceiling height can also play a role in sizing an AC or furnace. This is because ceilings over eight feet increase the volume of air in a room and require larger HVAC systems to maintain comfort.
Number of People
The more people you have in your home regularly can impact the size of the HVAC system you need. Each person adds heat to your home, which requires a higher cooling capacity. So, the more people, the larger the system you will need.
Lifestyle
Your lifestyle affects the size of the HVAC system you will need in a few ways. If you frequently entertain, you may need a slightly bigger HVAC system to accommodate a higher number of people in your house. If you prefer very low temperatures in the summer or high temperatures in the winter, you should consider this when choosing a system.
Climate
The location of your home also plays a big role in your heating and cooling needs. Homes in areas with extreme heat, for instance, need a more powerful AC than those in temperate climates.
